Inside the /home/java directory, jdk is a symlink to the current Java SDK install and ant is a symlink to the current Ant install. This means that the contents of /etc/profile.d/java.sh doesn't change when I install a new version of the JDK: I merely switch the sdk symlink at the same time as I unpack the download. >> Also, a pain in the ass is I must change directory to where the source >> file resides to compile.
